User Manager, Inbound Routes, Extensions,..all show "no matching records found"

Not sure what happened, but after I did a Framework and Core update, I found I was no longer able to access the User Manager, Inbound Routes, Extensions, and many other pages such as IVR and System Recordings; they all present the red Error sign in teh upper-right corner.

The strange thing is that the call traffic is fine. Calls come in and out and are routed through to the ring group, and calls outside of operating hours are answered with the IVR.

I spent about five hours today combing through the freepbx forums, trying different commands I recognized, but nothing helped. I also restored the backup from two days ago and that didn;t solve the issue either.

Thank you for whatever advice you can provide. I'd post a log or two but I'm not sure which ones to post. I've only been involved with Asterisk/Freepbx for a little over a year.
